the test result also reveals the saltheaving mechanism in sulphate salty soil under different initial dry density. it shows why sulphate salty soil heaving ratio changes with the initial dry density.
通过试验成果分析得出了不同初始干密度条件下的盐胀机理,揭示了盐胀率随不同初始干密度而变化的本质。
hydraulic retaining walls in seasonal cold region are often destroyed by breaking, declining and movement resulted from soil heaving behind walls.
